Hi Craiigman, this is now logged and under review. I've found the same instances across all attacking set pieces, when switching from left to right sides it flips the player positions hence rb at lb in your 2nd photo. What is reflect on the tactics board will happen in the game so whilst this is being fixed you will have to manually change your defensive positions.

Hey rc1269, this feature is intention , only the manager of a team (including U23/U18's) can select the captains.
If you have any real life examples were a first team manager has set captaincy through the res/youth please send it my way as I could put in a request for it to be reflected in the game.
